A wheel (radius 0.6 m) is rolling on a horizontal surface with a center of mass acceleration of 0.7 m/s2. If the force applied to the center of the wheel is 36.942 N and the wheel has a mass of 12.508 kg, what is the friction force acting between the wheel and the surface?
An elevator cable can withstand a maximum tension of 19,500N before breaking. The elevator has a mass of 480 kg and a maximum acceleration of 2.24 m/s2. Engineering safety standards require that the cable tension never exceed two-thirds of the breaki..
